Description The field experiments were conducted at the Indian Agricultural Research Institute, New Delhi for 3 years from 2002 to 2004 to study the effects of incorporation of 6 tonnes/ha of residue of wheat crop on the efficiency of diammonium phosphate (DAP) and Mussoorie rock phosphate plus inoculation of phosphorus-solubilizing bacteria (MRP + PSB) on summer mungbean var. ‘PS 16’. Application DAP @ 17.5 and 35 kg P/ha significantly increased seed yield over control by 16–34 and 39–49%, respectively, P uptake by 18–26 and 35–44%, respectively, gross returns by 13–25 and 32–41%, respectively and net return of mungbean by 23–288 and 87–278%, respectively, whereas application MRP + PSB @ 17.5, 35 and 52.5 kg P/ha increased seed yield over control by 9–17, 24–31 and 40–70%, respectively, P uptake by 7– 16, 23–35 and 38–51%, respectively, gross returns by 8–13, 18–28 and 37–56%, respectively and net returns of mungbean by 14–138, 43–146 and 85–678%, respectively. Thus, MRP + PSB at 35 and 52.5 kg/ha was at par with DAP at 17.5 and 35 kg/ha, respectively in terms of seed yield, P uptake and gross and net returns of mungbean. Agronomic efficiency ranged between 5.3 and 10.1 kg seed/kg P for DAP and between 3.1 and 6.3 kg seed/kg P for MRP + PSB. Similarly, apparent recovery of MRP + PSB was lower (3.4–7.0%) than that of DAP (7.0–10.2%). However, incorporation of residue of preceding wheat crop significantly increased the efficiency of MRP + PSB and thus MRP + PSB along with residue incorporation can be used for P fertilization in mungbean crop.
